The present invention relates to a timepiece including a first indicator displaying a first piece of information, a first mechanism for driving the first indicator, a second indicator displaying a second piece of information, a second mechanism for driving the second indicator, a correction mechanism and a device for correcting the second piece of information (10), said correction mechanism being arranged so as to be capable of simultaneously correcting the two pieces of information or only the first piece of information. The mechanism for driving the second indicator includes a differential gear (20) arranged so as to engage with the device for correcting the second piece of information (10) and with the first drive mechanism, such that the device for correcting the second piece of information (10) is arranged so as to occupy two positions, a first rest position, in which the correction mechanism, when actuated alone, corrects both the first and the second pieces of information, and a second correction position, in which the device for correcting the second piece of information (10) is arranged to fulfill two correction functions, i.e. a first function for correcting the second piece of information, according to which the device for correcting the second piece of information (10) engages with the second mechanism for driving the second indicator so as to correct only the second piece of information, the correction mechanism not being actuated, and a second correction function for correcting the first piece of information, according to which the device for correcting the second piece of information (10) engages with the second mechanism for driving the second indicator such that only the first piece of information is corrected when the correction mechanism is actuated at the same time as the device for correcting the second piece of information (10) is retained in the second position thereof.

The invention relates to a mechanism for driving an indicator of information that is connected to a timepiece movement and varies according to a plurality of periods, during each of which said information changes, step by step, to a maximum value that varies between n and n-m. Said mechanism includes a drive wheel (8) including a first set of gear teeth (10) arranged such as to advance by n steps per period, m retractable teeth (20, 21, 22) borne by the drive wheel (8), encoding cams corresponding to the retractable teeth (20, 21, 22), each encoding cam corresponding to at least one maximum value n-x of the information, x being between 1 and m, for a period, and a drive means set up such as to provide adequate rotation speed to the encoding cams relative to the drive wheel (8) in such a manner that, when the information reaches a maximum value n-x for a period, x retractable teeth (20, 21, 22) pass in an operative position and then return to an inoperative position, the drive wheel (8) advancing by x additional steps for said period. Each retractable tooth (20, 21, 22) includes a pin (30, 38, 42), and the corresponding encoding cam (26, 32, 34), corresponding to a maximum value n-x of the information, includes a track (28, 36, 40) wherein the pin (30, 38, 42) moves. The track (28, 36, 40) has a configuration that is appropriate for the retractable tooth (20, 21, 22) to remain in the inoperative position thereof in each period for which the maximum value corresponding to the information is a value between n-x+1 and n. Said configuration is moreover appropriate for the retractable tooth (20, 21, 22) to change from the inoperative position thereof to the operative position thereof, in each period for which the maximum value corresponding to the information is a value between n-m and n-x, and then return to the inoperative position thereof after engaging with said second drive pinion (2).
